VSL and C++ Reference Sample Progress

VSL and C++ Reference Sample Progress

The C++ Package and Menu and Commands Reference Samples have been coded, and scenario test development is in progress for those samples. The Visual Studio Library aka VSL now provides IVsPackageImpl, IVsInstalledProductImpl, and IOleCommandTargetImpl.

Work on the C++ Tool Window Reference Sample has begun, and the development of that sample will further expand VSL.
